Accounting Policies [Abstract]
Basis of Accounting	Basis of Accounting and Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. As an investment company, the Fund follows accounting and reporting guidance as set forth in Topic 946 (“Financial Services - Investment Companies”) of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification, as amended (“ASC”).

Actual results could differ from those estimates. As an investment company, the Fund follows accounting and reporting guidance as set forth in Topic 946 (“Financial Services - Investment Companies”) of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification, as amended (“ASC”).
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and money market mutual funds with maturities of, or the ability to redeem or liquidate holdings within, 90 days or less. Cash and cash equivalents are held in three bank accounts with two financial institutions, Mitsubishi UFJ Financial Group, Inc. ("MUFG Bank") and U.S. Bank National Association (“US Bank”), and as a result are subject to custodial concentration risk for cash and cash equivalents. Any cash held at US Bank in excess of the Federal Deposit Insurance Corporation (“FDIC”) limit of $250,000 is uninsured by the FDIC, while all cash held at MUFG Bank is uninsured by the FDIC. Money market mutual funds held as cash equivalents are valued at their most recently traded net asset value.
Interest on Loans	Interest on Loans Interest income on loans is recognized on an accrual basis using the effective interest method including amounts resulting from the accretion of discount on loans included as additional compensation as part of the loan agreements. Additionally, fees received as part of the transaction are added to the loan discount and accreted over the life of the loan.
Realized Gains and Losses from Loans	Realized Gains and Losses from Loans Realized gains or losses on the sale of loans are computed using the difference between the amortized cost and the sales proceeds. Realized losses on loan write-offs are recognized when management determines that a loan is uncollectible.
Investment Valuation	Investment Valuation The Fund accounts for loans for which market quotations are not readily available at fair value as determined in good faith by the Manager, who has been appointed as the Fund's valuation designee, pursuant to Rule 2a-5 under the 1940 Act. Subject to the oversight of the Fund's Board, all valuations are determined under the direction of the Manager, in accordance with the valuation methods described below and Rule 2a-5. As of March 31, 2025 and December 31, 2024, the financial statements included nonmarketable investments of $129.8 million and $151.1 million, respectively (or 93.4% and 94.4% of total assets, respectively), with the fair values determined by the Manager in the absence of readily determinable market values. Because of the inherent uncertainty of these valuations, estimated fair values of such investments may differ significantly from the fair values that would have been used had a readily available market for the securities existed, and the differences could be material. Below is the information used by the Manager in making these estimates. Loans The Fund defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the “most advantageous market”). Because there is no readily available market price and no secondary market for substantially all of the debt investments made by the Fund in its borrowing portfolio companies, Management determines fair value based on a transaction that would occur in the most advantageous market, and on several factors related to each borrower, including, but not limited to, the borrower’s payment history, available cash and “burn rate,” revenues, net income or loss, the likelihood that the borrower will be able to secure additional financing in the future, and an evaluation of the general interest rate environment. The amount of any valuation adjustment considers the estimated amount and timing of cash payments of principal and interest from the borrower and/or liquidation analysis and is determined based upon a credit analysis of the borrower and an analysis of the expected recovery from the borrower, including consideration of factors such as the nature and quality of the Fund’s security interests in collateral, the estimated fair value of the Fund’s collateral, the size of the loan, and the estimated time that will elapse before the Fund achieves a recovery. Where the risk profile is consistent with the original underwriting, the cost basis of substantially all of the loans approximates fair value. Management has evaluated these factors and has concluded that the effect of deterioration in the quality of the underlying collateral, increase in size of the loan, increase in the estimated time to recovery and increase in the market coupon rate would have the effect of lowering the fair value of the current portfolio of loans. Non-Accrual Loans The Fund’s policy is to classify a loan as non-accrual when the portfolio company is delinquent for three consecutive months on its monthly loan payment or for a lesser timeframe, if, in the opinion of Management, the portfolio company either ceases or materially curtails its operations and Management deems that it is unlikely that the loan will return to performing status. When a loan is placed on non-accrual status and the related interest is determined to not be collectible, all interest previously accrued but not collected is reversed. Any future interest received by the Fund on non-accrual loans will be recognized as interest income if and when the proceeds exceed the book value of the respective loan. If a borrower of a non-accrual loan resumes making regular payments and Management believes that such borrower has regained the ability to service the loan on a sustainable basis, the loan is reclassified back to accrual or performing status. Interest that would have been accrued during the time a loan was classified as non-accrual will be added back to the remaining payment schedule, causing a change in the effective interest rate. As of March 31, 2025 and December 31, 2024, loans with a cost basis of $107.5 million and $95.5 million and a fair value of $63.0 million and $53.8 million, respectively, were classified as non-accrual. Warrants and Equity Securities Warrants and equity securities received in connection with loan transactions are considered to be free standing contracts that are both legally detachable and separately exercisable from the related loan transactions and are measured at fair value at the time of acquisition. Warrants are valued based on a Black-Scholes option pricing model which considers, among several factors, the underlying stock value, expected term, volatility, and risk-free interest rate. It is anticipated that such securities will be distributed by the Fund to the Company simultaneously with, or shortly following, their acquisition. The underlying asset value is estimated based on available information. Volatility, or the amount of uncertainty or risk about the size of the changes in the warrant price, is based on an index of publicly traded companies grouped by industry and which are similar in nature to the underlying portfolio companies issuing the warrant (“Industry Index”). The volatility assumption for each Industry Index is based on the average volatility for individual public companies within the portfolio company’s industry for a period of time approximating the expected life of the warrants. An increase in the volatility of the warrants used in the Black-Scholes option pricing model would have the effect of increasing the fair value of the warrants. The remaining expected lives of warrants are based on historical experience of the average life of the warrants, as warrants are often exercised in the event of acquisitions, mergers, or initial public offerings and terminated due to events such as bankruptcies, restructuring activities, or additional financings. These events cause the expected term to be less than the remaining contractual term of the warrants. As of March 31, 2025 and December 31, 2024, the Fund assumed the average duration of a warrant is four years. The effect of an increase in the estimated initial term of the warrants used in the Black-Scholes option pricing model would have the effect of increasing the fair value of the warrants. However, the estimated initial term of the warrants is one factor, of many, used in the valuation of warrants, and by itself does not have a significant impact on the results of operations. The risk-free interest rate is derived from the constant maturity tables issued by the U.S. Treasury Department. The effect of an increase in the estimated risk-free rate used in the Black-Scholes option pricing model would have the effect of increasing the fair value of the warrants.
Other Assets and Liabilities	Other Assets and Liabilities Other assets include costs incurred in conjunction with borrowings under the Fund’s debt facility. These costs are amortized over the term of the facility using the straight-line basis. The amortization of these costs is recorded as interest expense in the Condensed Statements of Operations. The fair values of other assets and accrued liabilities are estimated at their carrying values because of the short-term nature of these assets and liabilities. The carrying value of the borrowings under the debt facility approximates their fair value based on the borrowing rates available to the Fund.
Commitment Fees	Commitment Fees Unearned income and commitment fees on loans are recognized using the effective-interest method over the term of the loan. Commitment fees are carried as liabilities when received for commitments upon which no draws have been made. When the first draw is made, the fee is treated as unearned income and is recognized as described above. If a draw is never made, the forfeited commitment fee less any applicable legal costs becomes recognized as other income after the commitment expires.
Derivative Instruments	Derivative Instruments The Fund used derivative instruments to manage its exposure to changes in interest rates on expected borrowings under its debt facility, as the Fund originates fixed rate loans (see Note 8). Derivative instruments were carried at fair value based on the quotes obtained from banks, brokers and dealers and adjusted for counterparty risk and the optionality of the interest rate terms. The valuation of the derivative instruments also considered the future expected interest rates on the notional principal balance remaining which was comparable to what a prospective acquirer would pay on the measurement date. Valuation pricing models considered inputs such as forward rates, anticipated interest rate volatility relating to the reference rate, as well as time value and other factors underlying derivative instruments. The Fund was a party to master netting arrangements with Zions Bancorporation, N.A., however, the Fund had elected not to offset assets and liabilities under these arrangements for financial statement presentation purposes. Contracts were recorded at gross fair value in either derivative assets or derivative liability in the Condensed Statements of Assets and Liabilities, depending on whether the fair value of the contract was in favor of the Fund or the counterparty. The changes in fair value were recorded in net change in unrealized gain (loss) from derivative instruments in the Condensed Statements of Operations and the monthly interest received or paid on the contract, if any, were recorded in net realized gain (loss) from derivative instruments in the Condensed Statements of Operations. The Fund terminated all of its derivative contracts as of December 31, 2024.
Segment Reporting	Segment Reporting In accordance with ASC Topic 280 - Segment Reporting (“ASC 280”), the Fund has determined that it has a single operating and reporting segment. As a result, the Fund’s segment accounting policies are the same as described herein and the Fund does not have any intra-segment sales and transfers of assets.
Earnings per Share	Basic earnings per share are computed by dividing net increase (decrease) in net assets resulting from operations by the weighted average common shares outstanding. Diluted earnings (loss) per share are computed by dividing net increase (decrease) in net assets resulting from operations by the weighted average common shares outstanding, including the dilutive effects of potential common shares (e.g., stock options). The Fund has no instruments that would be potential common shares; thus, reported basic and diluted earnings (loss) per share are the same.
Tax Status	The Fund has elected to be treated as a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code of 1986 (the "Code") and operates in a manner to qualify for the tax treatment applicable to RICs. Failing to maintain at least 70% of total assets in "qualifying assets" will result in the loss of BDC status, resulting in losing its favorable tax treatment as a RIC. As of March 31, 2025, the Fund has met the BDC and RIC requirements. The Fund elected to be treated for federal income tax purposes as a RIC under the Code with the filing of its federal income tax return for 2019. In order to qualify for favorable tax treatment as a RIC, the Fund is required to distribute annually to its shareholder at least 90% of its investment company taxable income, as defined by the Code. To avoid federal excise taxes, the Fund must distribute annually at least 98% of its ordinary income and 98.2% of net capital gains from the current year and any undistributed ordinary income and net capital gains from the preceding years. The Fund, at its discretion, may carry forward taxable income in excess of calendar year distributions and pay a 4% excise tax on this income. If the Fund chooses to do so, all other things being equal, this would increase expenses and reduce the amount available to be distributed to its shareholder. The Fund will accrue excise tax on estimated undistributed taxable income as required. Dividends from net investment income and distributions from net realized capital gains are determined in accordance with U.S. federal income tax regulations, which may differ from those amounts determined in accordance with U.S. GAAP. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, they are charged or credited to paid-in-capital or accumulated net realized gain (loss), as appropriate, in the period that the differences arise. Temporary and permanent differences are primarily attributable to differences in the tax treatment of certain loans and the tax characterization of income and non-deductible expenses. These differences are generally determined in conjunction with the preparation of the Fund’s annual RIC tax return.

It is anticipated that such securities will be distributed by the Fund to the Company simultaneously with, or shortly following, their acquisition.

The underlying asset value is estimated based on available information.

Volatility, or the amount of uncertainty or risk about the size of the changes in the warrant price, is based on an index of publicly traded companies grouped by industry and which are similar in nature to the underlying portfolio companies issuing the warrant (“Industry Index”). The volatility assumption for each Industry Index is based on the average volatility for individual public companies within the portfolio company’s industry for a period of time approximating the expected life of the warrants.

The Fund terminated all of its derivative contracts as of December 31, 2024.

Segment Reporting

In accordance with ASC Topic 280 - Segment Reporting (“ASC 280”), the Fund has determined that it has a single operating and reporting segment. As a result, the Fund’s segment accounting policies are the same as described herein and the Fund does not have any intra-segment sales and transfers of assets.

Earnings per Share

Basic earnings per share are computed by dividing net increase (decrease) in net assets resulting from operations by the weighted average common shares outstanding. Diluted earnings (loss) per share are computed by dividing net increase (decrease) in net assets resulting from operations by the weighted average common shares outstanding, including the dilutive effects of potential common shares (e.g., stock options). The Fund has no instruments that would be potential common shares; thus, reported basic and diluted earnings (loss) per share are the same.

Tax Status

The Fund has elected to be treated as a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code of 1986 (the "Code") and operates in a manner to qualify for the tax treatment applicable to RICs. Failing to maintain at least 70% of total assets in "qualifying assets" will result in the loss of BDC status, resulting in losing its favorable tax treatment as a RIC. As of March 31, 2025, the Fund has met the BDC and RIC requirements. The Fund elected to be treated for federal income tax purposes as a RIC under the Code with the filing of its federal income tax return for 2019.

In order to qualify for favorable tax treatment as a RIC, the Fund is required to distribute annually to its shareholder at least 90% of its investment company taxable income, as defined by the Code. To avoid federal excise taxes, the Fund must distribute annually at least 98% of its ordinary income and 98.2% of net capital gains from the current year and any undistributed ordinary income and net capital gains from the preceding years. The Fund, at its discretion, may carry forward taxable income in excess of calendar year distributions and pay a 4% excise tax on this income. If the Fund chooses to do so, all other things being equal, this would increase expenses and reduce the amount available to be distributed to its shareholder. The Fund will accrue excise tax on estimated undistributed taxable income as required.

Dividends from net investment income and distributions from net realized capital gains are determined in accordance with U.S. federal income tax regulations, which may differ from those amounts determined in accordance with U.S. GAAP. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, they are charged or credited to paid-in-capital or accumulated net realized gain (loss), as appropriate, in the period that the differences arise. Temporary and permanent differences are primarily attributable to differences in the tax treatment of certain loans and the tax characterization of income and non-deductible expenses. These differences are generally determined in conjunction with the preparation of the Fund’s annual RIC tax return.
